# Annotated Example Go Program
|
|
|
|
```go
|
|
// package main is a special package
|
|
// it allows Go to create an executable file
|
|
package main
|
|
|
|
/*
|
|
This is a multi-line comment.
|
|
|
|
import keyword makes another package available
|
|
for this .go "file".
|
|
|
|
import "fmt" lets you access fmt package's functionality
|
|
here in this file.
|
|
*/
|
|
import "fmt"
|
|
|
|
// "func main" is special.
|
|
//
|
|
// Go has to know where to start
|
|
//
|
|
// func main creates a starting point for Go
|
|
//
|
|
// After compiling the code,
|
|
// Go runtime will first run this function
|
|
func main() {
|
|
// after: import "fmt"
|
|
// Println function of "fmt" package becomes available
|
|
|
|
// Look at what it looks like by typing in the console:
|
|
// go doc -src fmt Println
|
|
|
|
// Println is just an exported function from
|
|
// "fmt" package
|
|
|
|
// Exported = First Letter is uppercase
|
|
fmt.Println("Hello Gopher!")
|
|
|
|
// Go cannot call Println function by itself.
|
|
// That's why you need to call it here.
|
|
// It only calls `func main` automatically.
|
|
|
|
// -----
|
|
|
|
// Go supports Unicode characters in string literals
|
|
// And also in source-code: KÖSTEBEK!
|
|
//
|
|
// Because: Literal ~= Source Code
|
|
}
|
|
